Structural Studies on Heat Shock Protein 90 from Dictyostelium Discoideum and Oryza Sativa
(2018-05-09)
Molecular chaperones are proteins that interact with and aid in stabilization and activation of other proteins. Chaperones help proteins attain their three dimensional conformation, without forming a part of the final ...
Protein Engineering and Stabilization of HIV-1 Envelope Glycoprotein
(2018-05-09)
A number of viral diseases such as Hepatitis B, small pox, measles, rubella and polio have effective vaccines to control or eradicate them. HIV-1 is a lentivirus which infects human immune cells and leads to the disease ...
Structural Studies on the Role of Hinge involved in Domain Swapping in Salmonella Typhimurium Stationary Phase Survival Protein (SurE) and Sesbania Mosaic Virus Coat Protein
(2018-05-09)
A unique mechanism of protein oligomerization is domain swapping. It is a feature found in some proteins wherein a dimer or a higher oligomer is formed by the exchange of identical structural segments between protomers. ...
Small Heat Shock Proteins from Oryza Sativa and Salmonella Enterica
(2018-05-09)
Small heat shock proteins (sHSPs) are a ubiquitous family of molecular chaperones that play a vital role in maintaining protein homeostasis in cells. They are the first line of defence against the detrimental effects of ...
Structural and Related Studies on Mycobacterial Lectins
(2018-05-09)
This thesis is concerned with the first ever X-ray crystallographic and complimentary solution studies on mycobacterial lectins. Lectins, described as multivalent carbohydrate binding proteins of non-immune origin, are ...
Biochemical, Biophysical and Evolutionary Perspectives of Zinc Finger Proteins in Mycobacterium smegmatis
(2018-05-21)
Transcription is a major step in expression of genes of a given organism. Due to environmental constrains this step must be regulated in the favour of the sustenance and growth of the organism. Here comes the relevance of ...
Design and Characterization of HIV-1 ENV Derived Immunogens
(2018-06-21)
The Human Immunodeficiency Virus (HIV) is a member of the retroviridae family from lentivirus genus which primarily infects CD4+ T cells and also to lesser degree monocytes, macrophages, and dendritic cells causing progressive ...
Structural and Functional Studies on the Mycobacterium tuberculosis σ factor σJ
(2018-05-21)
Regulation of transcription in prokaryotes is primarily governed at the transcription initiation step. This feature has been extensively characterized in model prokaryotes notably Escherichia coli and Bacillus subtilis. ...
Modulation of Protein Stability and Function by Cysteine Mutations and Signal Peptides
(2018-06-23)
Chapter 1gives a general introduction to the CXXC motif found in natural proteins. It then reviews the studies where disulphides were engineered in various proteins. The various strategies developed to engineer metal binding ...
Structural Feature of Prokaryotic Promoters and their Role in Gene Expression
(2018-05-14)
Transcription initiation is an important step in the process of gene regulation in prokaryotes. Promoters are stretches of DNA sequence that are present in the upstream region of transcription start sites (TSSs), where RNA ...
